ABU DHABI, UAE, April 29, 2024 /PRNewswire/ -- Huasun Energy, the
world's largest heterojunction (HJT) product manufacturer, has
unveiled its latest innovation in high-efficiency modules,
featuring groundbreaking zero busbar (0BB) technology. This
cutting-edge advancement has been seamlessly integrated into
Huasun's mass production lines, including the Himalaya G12 Series
and Everest G12R Rectangular Series of large-format modules.
Leveraging innovative improvements in printing processes,
front-layer welding, fine solar ribbons, ultra-thin silicon wafers,
encapsulation, and sealing techniques, Huasun has significantly
elevated the electrical, optical, and temperature coefficient
performance of HJT modules, enhancing the market competitiveness of
its product lineup.
While 0BB technology is advancing towards industrialization,
variations exist among companies regarding specific implementation
methods. Huasun's approach primarily involves welding and
dispensing, incorporating advantages such as stronger adhesion,
improved resistance to hot spots, and elimination of carrier
film.
Specifically, regarding the manufacturing process of 0BB cells,
Huasun adopts a simpler two-step screen print (SP) technology to
deliver superior product quality and enhanced electrical and
cell-to-module (CTM) performance, demonstrating significant
advantages over super multi-busbar (SMBB) products in terms of
open-circuit voltage (OCV), conversion efficiency and module power
output.
"Huasun's 0BB modules employ front-layer welding, which offers
benefits including reliable soldering, reduced contact resistance,
enhanced resistance to hot spots, lower hot-spot temperature, and
higher module reliability. Additionally, the design reduces metal
coverage on the back, expanding the light-receiving area and
achieving bifaciality of up to 90%," added Christian Comes, Huasun's BD Director
Europe.
The 0BB technology supports the trend towards thinner silicon
wafers by providing higher reliability with no main grid, thinner
ribbons, minimal stress, and lower fragmentation rates. By
leveraging the downshifting (DS) light conversion encapsulation and
PIB edge sealing technology, Huasun's HJT 0BB modules deliver a
substantial increase in power generation capacity. This advancement
translates into more dependable products for owners of photovoltaic
projects across utility, commercial & industrial (C&I), and
residential rooftops.
The successful mass production of "G12+0BB" and "G12+R+0BB" HJT
products signifies another milestone for Huasun in its quest for
efficiency enhancement. Committed to advancing the
industrialization of HJT technology, Huasun continues to promote
the widespread adoption of 0BB high-efficiency modules, providing
the-state-of-art heterojunction products with higher conversion
efficiency, enhanced reliability, and lower Levelized Cost of
Electricity (LCOE) for the PV projects worldwide.
